SPECIFICATION forming part of Letters Patent No. 466,971, dated January12, 1892.

Application filed December 22,1890. Serial No. 375,462- (No model.) i

To all whom it may concern: 1

Be it known that we, HARRISON M. ANGLE and WINTER D. HEss, of Evanston,in the county of Cook and State of Illinois, have invented a new,useful, and Improved Lubrieating Device for Elevator-Guides, of whichthe following is a full, clear, and exact description, reference beinghad to the acco1n panying drawings, forming a part of thisspecification, in which-- Figure 1 is a side View of an elevator,showing the usual guide-posts and our improved lubricating device inconnection therewith. Fig. 2 is a side view in detail of a portion ofthe elevator guide-beam and guide-post, respectively, showing ourimproved lubricating device applied thereto. Fig. 3 is a similar viewshowing said lubricating device in vertical section. Fig. 4 is a planView of said lubricating device as it appears in connection with theguide-post, the latter being shown in transverse section. Fig. 5 is ahorizontal sec-V tional view in detail of said lubricating device; andFig.6 is a sectional detail View taken upon the line 5c 50, Fig. 5,viewed in the direction of the arrow there shown.

Corresponding letters. of reference in the different figures indicatelike parts.

Much trouble has been heretofore experienced in the operation ofelevators and lifts owing to the difficulty of keeping the guidepostsproperly lubricated. As the weight in the car is liable to be constantlyshifted and is rarely balanced, any deficiency in the lubrication of theguide-posts is not only liable to interfere with the running of the carby causing it to jump, as a result of excessive friction, but to wearthe guide-posts and render the surface thereof uneven. To overcome theseobjections, lubricate the guideposts evenly and uniformly, and enablethe car to run smoothly and easily is the object of our invention,whichobject we accomplish in the manner hereinafter more particularlydescribed and claimed.

Referring to the drawings, a represents an ordinary passenger-elevator,of which I) b are the usual transverse guide-beams arranged at thebottom and top, respectively, said guide-beams being notched orbifurcated at the ends to engage with the usual vertical guide-posts cc. To the respective ends of said guidenbeams, and preferably at the topthereof, as shown in Figs. 1 and 2, we attach our improved lubricatorsd.Each of said lubricators consists of a frame preferably cast in onepiece and comprising a main portion 8 and two wings e 6, arranged atright angles thereto, so as embrace the three exposed faces of theguide-post. At the corners of said frame, where the wings are joined tothe main body e, are perforations ff, by means of which said frame maybe rigidly attached with bolts ff' to the guide-beam.

\Vithin the three portions 6 e e of the frame are formed recesses orcavities g h h, respectively, (shown in Fig. 5 and indicated by dottedlines in Fig. 4,) which have their openings presented toward theguide-post. Vithin the cavity 9 is placed a rollerj, adapted to pressagainst the front face of the guidepost 0, as shown in Figs. 3and4=,while Within the recesses h h are placed like rollers 75 1:, adaptedto press in like manner against the side faces, respectively, of saidguide-posts. At the respective ends of each of said several recesses areformed parallel guides Z Z, between which are loosely placed slidingblocks Z Z. Between said blocks and the back of the frame are interposedspiral springs m, Figs. 3, 5, and 6, which tend to push said blocksforward toward the outer ends of the guides. The blocks Z, with theguides Z, serve as rests for the projecting axes of the respectiverollers, as clearly shown in Fig. 5.

On top of the frame is placed an oil-cup n, the outlet of which isconnected with a tube 0, bent to conform to the shape of the frame, asshown in Fig. 4, and communicating by means of ducts 0', Fig. 3, alsoindicated in dotted lines in Fig. 4, with the recesses g h h, directlyover the rollers j 7c 70, so that the oil in dropping therein falls uponsaid rollers, and as the latter are pressed against the guideposts 0, bymeans of the springs m,said posts are kept constantly lubricated as theelevator moves up and down, the rollers being pressed constantly againstthe posts, regardless of the manner in which the load is distributedupon the elevator. It will thus be seen that it is only necessary tokeep the oil-cups filled in order to maintain automaticallya perfect anduniform lubrication of the guide-posts.

We are aware that it is not, in a broad sense, new to use a roller fordistributing oil over a surface to be lubricated, and do not claim suchas our invention.

Having thus described our invention, We.

1. The combination, with an elevator-cage naled in the wings e e,respectively, means for forcing said rollers into contact with the facesof the guide opposite which they are respectively arranged, and meansfor supplying oil directly to said rollers, by which latter it isdistributed over the guide, substantially as set forth.

2. The combination, with an elevator-cage and the guide-post thereof, ofa lubricator having a suitable frame, a roller journaled in said frame,means for forcing said roller against the face of the guide with ayielding pressure, and an oil-cup having its discharge situated directlyover the roller, so as to supply oil to its periphery drop by drop,substan- V tially as set forth.

3.The combination, with an elevator-cage and a guide-post,jof alubricator consisting of a frame comprising the main portion e, havingrecess 9 opening toward the front face of the guide-post, and the wingse e having recesses h h opening toward the opposite side faces of saidpost, respectively, a roller situated in each of said recesses, meansfor holding said rollers with a yielding pressure in contact with thefaces of the guide oppo site which they are respectively arranged, andmeans for supplying them with oil, substantially as set forth.

4. The combination, with an elevator-cage and a guide-post, of alubricator consisting of a frame comprising the main portion 6, havingrecess g opening toward the front face of the guide-post, and the wingse e, having recesses h h opening toward the opposite side faces of saidpost, respectively, a roller situated in each of said recesses, meansforholding said rollers with a yielding pressure in contact with the facesof the guide opposite which they are respectively situated, and meansfor supplying oil directly to the pe riphery of each of said rollers,substantially as set forth. 7

5. The combination, with an elevator-cage and the guide-post, of alubricator consisting of a frame comprising the portion e, having therecess g opening toward the front face of the guide-post, the wings e 6,having recesses 71. h opening toward the opposite side faces of saidpost, respectively, the parallel guides Z Z, situated at the ends ofsaid recesses, the rollers j k 70, situated in said recesses and havingjournals projecting between said guides, the follower-blocks Z Z,situated between said guides and engaging said journals, the springs m,engaging said blocks and forcing them outward, and means for supplyingthe rollers with oil, substantially as set forth.

6. The combination, with an elevator-cage and the guide-post, of alubricator consisting of the integral frame comprising the portion e,having the recess 9 opening toward the front face of the guide-post, thewings e 6, having recesses h h opening toward the opposite side faces ofsaid post, respectively, the parallel guides Z Z, situated at the endsof said recesses, the rollers j kit, situated in the re- 7 engaging saidjournals, the springs m, engagingsaid blocks and forcing them outward,the oil-cup 'n, situated on top of the frame, and the tube 0, havingducts 0' 0' 0' opening into the respective recesses directly over therollers, substantially asset forth.

Intestimony whereof we have signed this specification, in the presenceof two subscribing witnesses.
